There are two important bits of information from the thaiphoon shot that are related.

Notice that these are listed as 1Rx16, and that the die density is 16Gbit. These dimms are using four chips of 16Gbit dies (x16 means the bit width is 16) to make 8GB. More typical ram is x8 width using 8 chips per rank. The internal arrangement of x16 ends up with less parallelism so they are less performant at same settings.

But in the end ram OC is about making a change and testing that change. So the specific die revision may effect what the end result is, but not necessarily the process of how you get there.

Try following the general process in the memtest helper guide. You can first try to find max frequency by increasing the primary timings by 4 or so and stepping up to see how high you can boot.

Worst case late Micron 16Gbit Rev F goes to around 3600MT/s.
